Measurements of height and depth of femoral tunnels by a modified quadrant method.a
| Group 1 | Group 2 | Group 3 | Group 4 | |
|---|---|---|---|---|
| AM depth (%)* | 26.8 ± 4.0 | 28.1 ± 3.0 | 33.2 ± 2.9 | 30.6 ± 3.0 |
| AM height (%)* | 12.6 ± 3.8 | 14.2 ± 4.4 | 19.5 ± 3.3 | 17.4 ± 3.7 |
| PL depth (%) | 34.5 ± 1.9 | 37.1 ± 1.6 | 41.2 ± 3.2 | 43.8 ± 1.9 |
| PL height (%)* | 35.4 ± 2.7 | 38.2 ± 2.8 | 41.0 ± 2.5 | 40.8 ± 2.8 |
* Analysis of variance was used to statistically analyse the differences among the four groups. The significance was determined at p < 0.05.
AM = anteromedial; PL = posterolateral.

All parameters were calculated by the modified quadrant method. If the tunnel placement is higher or shallower in knee flexion position, the parameter will be smaller.
